A display device according to exemplary embodiments includes: a display panel including: a first opening and a second opening and displaying an image; a first crack sensing line disposed around the first opening; and a second crack sensing line disposed around the second opening, wherein a crack around the first opening is sensed by disconnection of the first crack sensing line, and a crack around the second opening is sensed by disconnection of the second crack sensing line.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A display device comprising: a display panel including a first opening and a second opening; a first crack sensing line disposed around the first opening; and a second crack sensing line disposed around the second opening, wherein the first opening and the second opening are surrounded by a display area displaying an image, wherein a crack around the first opening is sensed by disconnection of the first crack sensing line, and wherein a crack around the second opening is sensed by disconnection of the second crack sensing line.
2. The display device of claim 1 , wherein a first end of each of the first crack sensing line and the second crack sensing line receives a sensing voltage through a voltage applying signal line.
3. The display device of claim 2 , wherein: a second end of the first crack sensing line is connected to a first detection signal line; and the first detection signal line is connected to a first data line.
4. The display device of claim 3 , wherein: a second end of the second crack sensing line is connected to a second detection signal line; and the second detection signal line is connected to a second data line.
5. The display device of claim 4 , wherein the display panel includes: a lower display unit including a bending portion and a driver; and an upper display unit disposed on the lower display unit.
6. The display device of claim 5 , wherein: the lower display unit includes the display area including a pixel and a peripheral area disposed around the display area; the bending portion and the driver are disposed in the peripheral area; and the bending portion and the driver are protruded from a side of the display area.
7. The display device of claim 6 , wherein the pixel includes an organic light emitting diode and a diode driving circuit supplying a current to the organic light emitting diode.
8. The display device of claim 6 , wherein the voltage applying signal line includes a voltage applying line disposed in the upper display unit and a peripheral voltage applying line disposed in the lower display unit.
9. The display device of claim 8 , wherein the peripheral voltage applying line is formed across the bending portion of the lower display unit and the driver.
10. The display device of claim 8 , wherein the voltage applying line and the peripheral voltage applying line are electrically connected through a voltage applying line pad.
11. The display device of claim 8 , wherein the first detection signal line includes a first sensing line disposed in the upper display unit and a first peripheral sensing line disposed in the lower display unit.
12. The display device of claim 11 , wherein the first peripheral sensing line is formed across the bending portion of the lower display unit and the driver.
13. The display device of claim 12 , wherein the first sensing line and the first peripheral sensing line are electrically connected through a first sensing line pad.
14. The display device of claim 11 , wherein the second detection signal line includes a second sensing line disposed in the upper display unit and a second peripheral sensing line disposed in the lower display unit.
15. The display device of claim 14 , wherein the second peripheral sensing line is formed across the bending portion of the lower display unit and the driver.
16. The display device of claim 14 , wherein the second sensing line and the second peripheral sensing line are electrically connected through a second sensing line pad.
17. The display device of claim 5 , wherein the upper display unit includes a touch sensor for sensing a touch input.
18. The display device of claim 5 , further comprising a bending portion crack sensing wiring sensing a crack in the bending portion.
19. The display device of claim 1 , further comprising a display panel crack sensing wiring for sensing a crack formed in the display panel.
